Iziboniso ze-LED ziyiguqule indlela esihambisa ngayo ulwazi, ngaphakathi nangaphandle kuseto. Iintlobo ezimbini eziqhelekileyo zobuchwepheshe be-LED zilawula imarike: i-SMD (i-Surface-Mounted Device) i-LED kunye ne-DIP (i-Dual In-line Package) i-LED. Ngamnye uneempawu ezizodwa, kwaye ukwazi ukungafani kwabo kubalulekile ekwenzeni ukhetho olufanelekileyo ngokuxhomekeke kwisicelo sakho. Masicazulule ezi ntlobo zimbini zemiboniso ye-LED kwaye siphonononge ukuba zahluke njani ngokwesakhiwo, ukusebenza kunye nokusetyenziswa.
1. Ulwakhiwo lwe-LED
Umahluko osisiseko phakathi kwe-SMD kunye nee-LED ze-DIP ulele kubume bazo bomzimba:
Umboniso we-SMD we-LED: Kumboniso we-SMD, iitshiphusi ze-LED zixhonywe ngqo kumphezulu webhodi yesekethe eprintiweyo (PCB). I-LED enye ye-SMD ihlala iqulethe iidiode ezibomvu, eziluhlaza, eziluhlaza kwiphakheji enye, zenza ipixel.
Umboniso we-LED we-DIP: Ii-LED ze-DIP zibandakanya iidiode ezibomvu, eziluhlaza, kunye nebhlowu ezifakwe kwiqokobhe leresin eqinile. Ezi LEDs zixhonywe kwimingxuma kwiPCB, kwaye idiode nganye yenza inxalenye yepixel enkulu.
2. Uyilo lwePixel kunye nobuninzi
Ulungiselelo lwee-LED luchaphazela ukuxinana kwepixel kunye nokucaca kwemifanekiso yazo zombini ezi ndidi:
SMD: Ngenxa yokuba zontathu iidiode (RGB) ziqulethwe kwiphakheji enye encinci, ii-LED ze-SMD zivumela ubuninzi be-pixel enkulu. Oku kubenza balungele iziboniso eziphezulu apho iinkcukacha ezintle kunye nemifanekiso ebukhali ifunekayo.
I-DIP: Umbala ngamnye we-diode ubekwe ngokwahlukileyo, othintela ubuninzi be-pixel, ngakumbi kwimiboniso yepitch encinci. Ngenxa yoko, ii-LED ze-DIP ziqhele ukusetyenziswa kwizicelo apho isisombululo esiphezulu singeyona nto iphambili, njengezikrini ezinkulu zangaphandle.
3. Ukuqaqamba
Ukukhanya yenye into ebalulekileyo xa ukhetha phakathi kwe-SMD kunye ne-DIP ye-LED ibonisa:
I-SMD: Ii-LED ze-SMD zibonelela ngokuqaqamba okuphakathi, ngokuqhelekileyo zilungele iimeko zangaphakathi okanye ezingaphandle. Inzuzo yabo ephambili kukudibanisa umbala ophezulu kunye nomgangatho womfanekiso, kunokukhanya okugqithisileyo.
I-DIP: Ii-LED ze-DIP ziyaziwa ngokuqaqamba kwazo okukhulu, zizenza zilungele usetyenziso lwangaphandle. Banokugcina ukubonakala okucacileyo ekukhanyeni kwelanga, enye yezona zinto zibalulekileyo kubo kwitekhnoloji ye-SMD.
4. Iengile yokujonga
I-engile yokujonga ibhekisa kwindlela ekude kangakanani embindini onokujonga ngayo isiboniso ngaphandle kokuphulukana nomgangatho womfanekiso:
I-SMD: Ii-LED ze-SMD zibonelela nge-angle yokujonga ebanzi, rhoqo ukuya kuthi ga kwi-160 degrees ngokuthe tye nangokuthe nkqo. Oku kubenza babe lukhetho oludumileyo kwimiboniso yangaphakathi, apho abaphulaphuli bajonga izikrini ukusuka kwii-engile ezininzi.
I-DIP: Ii-LED ze-DIP zikholisa ukuba ne-engile yokujonga emxinwa, ngokuqhelekileyo malunga ne-100 ukuya kwi-110 degrees. Ngelixa oku kwanele kwisetingi zangaphandle apho ababukeli baqhele ukude, ayilunganga kangako xa ijongwa ngokusondeleyo okanye ngaphandle kwe-angle.
5. Ukuqina kunye nokumelana neMozulu
Ukuqina kubalulekile, ngakumbi kwimiboniso yangaphandle ejongene neemeko zemozulu ezinzima:
I-SMD: Ngelixa ii-LED ze-SMD zifanelekile kusetyenziso oluninzi lwangaphandle, zincinci kunee-DIP ze-LED kwiimeko zemozulu ezimbi. Uyilo lwabo olunyuswe phezulu lubenza babe sesichengeni ngakumbi kumonakalo wokufuma, ubushushu, okanye iimpembelelo.
I-DIP: Ii-LED ze-DIP zihlala zihlala ixesha elide kwaye zibonelela ngokumelana nemozulu engcono. Isingxobo sabo se-resin esikhuselayo sibanceda ukuba bamelane nemvula, uthuli, kunye namaqondo obushushu aphezulu, nto leyo ebenza ukuba bakhethe ukufakwa okukhulu kwangaphandle okunje ngeebhilibhodi.
6. Ukusebenza kakuhle kwamandla
Ukusetyenziswa kwamandla kunokuba yinkxalabo yofakelo lwexesha elide okanye olukhulu:
I-SMD: Iziboniso ze-SMD zinamandla ngakumbi kuneziboniso ze-DIP ngenxa yoyilo oluphezulu kunye nobukhulu obuhlangeneyo. Bafuna amandla amancinane ukuvelisa imibala edlamkileyo kunye nemifanekiso eneenkcukacha, nto leyo ebenza ukhetho olufanelekileyo kwiiprojekthi ezijonga amandla.
I-DIP: Iziboniso ze-DIP zisebenzisa amandla amaninzi ukuphumeza amanqanaba abo okukhanya aphezulu. Oku kunyuka kwemfuno yamandla kunokukhokelela kwiindleko zokusebenza eziphezulu, ngakumbi kufakelo lwangaphandle oluqhuba ngokuqhubekayo.
7. Iindleko
Uhlahlo lwabiwo-mali ludlala indima ebalulekileyo ekugqibeni phakathi kwe-SMD kunye ne-DIP ye-DIP yemiboniso ye-LED:
I-SMD: Ngokuqhelekileyo, iziboniso ze-SMD zibiza kakhulu ngenxa yezakhono zabo eziphezulu kunye nenkqubo yokuvelisa. Nangona kunjalo, ukusebenza kwabo ngokuchaneka kombala kunye noxinaniso lwe-pixel luthethelela iindleko zezicelo ezininzi.
I-DIP: Iziboniso ze-DIP zifikeleleka ngokubanzi, ngakumbi kufakelo lwangaphandle olukhulu, olunokulungiswa okusezantsi. Ixabiso eliphantsi libenza ukuba babe lukhetho oludumileyo kwiiprojekthi ezifuna ukuqina kodwa hayi iinkcukacha ezintle.
8. Izicelo eziqhelekileyo
Uhlobo lwesiboniso se-LED osikhethayo siya kuxhomekeka kakhulu kwisicelo esicetywayo:
I-SMD: Ii-LED ze-SMD zisetyenziswa ngokubanzi kwimiboniso yangaphakathi, kubandakanywa namagumbi enkomfa, imiqondiso yokuthengisa, imiboniso yemiboniso yezorhwebo, kunye nezitudiyo zikamabonwakude. Zikwafunyanwa kufakelo oluncinci lwangaphandle apho isisombululo esiphezulu siyimfuneko, njengezikrini zentengiso ekufutshane.
I-DIP: Ii-LED ze-DIP zilawula ukufakelwa kwangaphandle okukhulu, okufana neebhilibhodi, izikrini zebala lemidlalo, kunye nemiboniso yemisitho yangaphandle. Uyilo lwabo olomeleleyo kunye nokuqaqamba okuphakamileyo kubenza bagqibelele kwindawo apho ukuqina okugqithisileyo kunye nokubonakala kokukhanya kwelanga kuyadingeka.
Isiphelo: Ukukhetha phakathi kwe-SMD kunye ne-DIP ye-LED Displays
Xa ukhetha phakathi komboniso we-SMD kunye ne-DIP ye-LED, kubalulekile ukuqwalasela iimfuno ezithile zeprojekthi yakho. Ukuba ufuna isisombululo esiphezulu, ii-engile zokujonga ngokubanzi, kunye nomgangatho womfanekiso ongcono, ngakumbi kwiisetingi zangaphakathi, iziboniso ze-SMD ze-LED yindlela yokuhamba. Kwelinye icala, kufakelo olukhulu lwangaphandle apho ukukhanya, ukuqina, kunye nokusebenza kakuhle kweendleko kubalulekile, iziboniso ze-DIP ze-LED zihlala zilolona khetho lungcono.
